10x for the info, but what about my first question ? I`ve clearly downloaded the open source version and when I type zmcontrol -v it returns Release 6.0.1_GA_1816.RHEL5_20090911181524 CentOS5 NETWORK edition.

And I assure you that I didn't install a network edition over the open source one and although it returns NETWORK EDITION it's not a network edition because in our company we already have a network edition one and these 2 differ from each other.

You might be able to get away with installing the SLES10 version on openSUSE 10.2, but any number of things could go odd with the install. Definitely take a backup of the server first if you try it. You might run into things like different library versions that can mess it up, but it's worth a try
